If you decided to purchase a Garmin car GPS, you can visit the garmin website and check out the list of their authorized dealers. All contact information about their dealers is included in their website. If in some cases your local dealer do not have available stocks or is not really selling their car gps, then you may opt to purchase online. The price of a garmin car gps ranges from 100$ up to 600$ depending on the type of model you wish to purchase. Inquire about shipment fees, if any, so you can prepare your money ahead of time. Not having a local garmin  gps dealer in your area doesn’t mean that their car gps doesn’t work there. The beauty of their car gps technology is that it can work anywhere around the world. You simply have to upload specific maps in your location and you are set to go.
